Initially Zjef focused on Performance Art for museums and galleries as well as for the gay
club scene in Amsterdam and Europe. He was one of the founders of the “Safe Sex Guerrilla”:
a group of guys brought together to raid gay clubs and spread Safe Sex Awareness in fun and
provocative performances. It was featured on both CNN and MTV with appearances and
interviews, and resulted in a touching documentary of 5 years on the road with that group.
